I am considering rewriting some parts of dejagnu(1) to use short Awk

because awk(1) is missing.
I have added an AC_PROG_AWK check to configure.ac. We can have
configure abort if there is no awk installed on the system.
We probably should do that -- as far as I can tell, not only is awk(1)
required by POSIX, but it was also present in all or nearly all
pre-POSIX systems. (If the GNU Coding Standards permit its availability
to be assumed, as they do...) I think that we can call a missing awk(1)
a system configuration error.
AC_PROG_AWK is more to *select* an Awk implementation than to ensure
that one exists. (Adding a similar search to dejagnu(1) is now on my
local TODO list.)
